Abstract: In this article, we present an algorithm to generate minimal cut sets from AltaRica 3.0 models. AltaRica 3.0 improves the previous versions of the language by introducing a fixpoint mechanism to stabilise values of variables after each transition firing. This fixpoint mechanism allows the design of acausal models and the analysis of systems with instant loops. It makes however the generation of fault trees more complex. We show here that by using advanced partitioning techniques, we can nevertheless design an efficient generation algorithm. We illustrate the different steps of this algorithm by means of a red wire example.
